Okay, it was already there, but I removed CONFIG_USB_MIDI this time (I'm 
using 'make menuconfig' and it doesn't mention this option being for OSS 
only, just FYI).

/usr/src/linux # egrep -i 'midi|snd|audio|usb' .config | grep -v ^#
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_HWDEP=y
CONFIG_SND_RAWMIDI=y
CONFIG_SND_SEQUENCER=y
CONFIG_SND_SEQ_DUMMY=y
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RTCTIMER=y
CONFIG_SND_VERBOSE_PRINTK=y
CONFIG_SND_DEBUG=y
CONFIG_SND_DEBUG_MEMORY=y
CONFIG_SND_DEBUG_DETECT=y
CONFIG_SND_VX_LIB=y
CONFIG_SND_VIRMIDI=m
CONFIG_SND_AC97_CODEC=y
CONFIG_SND_CS46XX=y
CONFIG_SND_CS46XX_NEW_DSP=y
CONFIG_SND_USB_AUDIO=m
CONFIG_SND_VXPOCKET=y
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_BANDWIDTH=y
CONFIG_USB_UHCI_HCD=y
CONFIG_USB_PRINTER=m
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y

Regardless of whether or not CONFIG_SND_USB_AUDIO is a module, I now 
only get:

usb 1-1: new full speed USB device using address 2

in /var/log/messages.  'modprobe snd-usb-audio vid=0x0582 pid=0x0015' 
doesn't help the situation.  'amidi -l' only shows me my Crystal 
SoundFusion card.

I also tried playing with CONFIG_SND_VIRMIDI, and if loaded / 
compiled-in, it also shows up in 'amidi -l', but doesn't help the 
snd-usb-audio situation (which is what I expected).  It doesn't show up 
in rosegardensequencer either, but I'm now using 'amidi -l' as the test 
since it's faster.

However, lsusb -v gives me:

which is the same as for the OSS driver, IIRC.

Talk about confusing/misleading advertising/literature!  Thanks for the 
clarification.
